Polycrystalline diamond compact (PDC) bits with multiple fixed cutters drill through deep formations and are used in oil and gas, geothermal, and mining industry. The bit-rock interaction excites drill string vibrations, which need to be mitigated to

The push in the drilling industry for drilling longer wells, and faster and more difficult trajectories leads to increasing challenges with the dynamics of the drilling systems in particular in expensive high end offshore wells. Dynamic effects are m

High vibrational loads occur due to self-excited high-frequency torsional oscillations (HFTO) that are excited by the bit-rock interaction while drilling in hard and dense formations. These critical vibration loads with an associated acceleration abo

Different vibration phenomena and vibration dysfunctions are excited by the drilling process. The associated dynamic loads result in downhole tool failures and inefficient drilling if not properly managed. Vibration mitigation strategies based on adj

High Frequency Torsional Oscillations (HFTO) generate high torsional loads in the BHA causing cracks, damaged electronics or twist-offs. A new Torsional Vibration Isolator tool (TVI) protects the BHA by restricting vibrations to the tools between bit

Vibrations impact the drilling process by reducing reliability, increasing maintenance costs and reducing rate of penetration and drilling efficiency. Herein, torsional vibrations are typically distinguished into low-frequency torsional oscillations

Self-excited torsional vibrations of the bottomhole assembly (BHA) at frequencies above 50 Hz, so-called "high-frequency torsional oscillations" (HFTO), can damage drilling tools and can increase non-productive time (NPT). A recently developed HFTO-i

During downhole drilling, severe vibration loads can occur that affect the reliability and durability of tools in bottom-hole assemblies (BHA). These high-frequency torsional oscillations (HFTO) can cause premature damage to tools or their subcompone

To reduce cost, drilling operations are getting longer, both in time and distance. Simultaneously, drilling parameters are optimized to reach higher performance for a maximum rate of penetration (ROP). The drawbacks of these practices are increased s
